Manage the DHCP Server Address Pool
By default, the modem router acts as a Dynamic Host Configuration Protocol (DHCP) server.
The modem router assigns IP, DNS server, and default gateway addresses to all computers
that are connected to its LAN and WiFi network. The assigned default gateway address is the
LAN address of the modem router.
These addresses must be part of the same IP address subnet as the modem router’s LAN IP
address. The default DHCP address pool is 192.168.0.2–192.168.0.254.
The modem router delivers the following parameters to any LAN device that requests DHCP:
•
An IP address from the range that you define
•
Subnet mask
•
Gateway IP address (the modem router’s LAN IP address)
•
DNS server IP address (the modem router’s LAN IP address)
To specify the pool of IP addresses that the modem router assigns:
1.
Launch an Internet browser from a computer or WiFi device that is connected to the
network.
2.
Type
.
A login screen displays.
3.
Enter the user name and password for the modem router.

settings of all your computers.
